Figure 4. Humidity and Barometric Pressure Do Not Affect Concussion Incidence.

Figure 4

(a) Bar graph shows mean dew point (SEM) for concussion and concussion-free games (p>0.05, NS). (b) Poisson regression computes the predicted concussion incidence of any given game played at a certain humidity. The environmental factors of temperature, dew point, humidity, and barometric pressure were utilized in the model.
